Ce掺杂单晶石榴石Ce:V:(Gd, Y)3Al5O12是一种实现高亮度、 高分辨率红色显示的理想荧光新材料。 它具有宽带发光谱, 主峰位于580 nm, 采用这种材料作荧光屏的φ54 mm阴极射线管投影管可以达到7300 cd/m2的高亮度, 效率为1.5 lm/W, 通过优化电子枪设计, 整管分辨率可达到80 line/mm以上。 本文对这种新材料的发光机理、 制备工艺进行了详细介绍, 并对一些实验中得到的有意义的结论进行了报道。

A cerium-activated garnet Ce:V:(Gd, Y)3Al5O12 with maximum intensity of broad red-band emission at 580 nm is a newly-developed luminescent material suitable for high brightness and high resolution display. The 2-inch CRT projection tube with the luminescent screen made of this material has reached the maximum brightness of 7300 cd/m2 with a efficiency of 1.5 lm/W. By optimum-designed electron gun the resolution of this tube can be more than 80 lines per millimeter clearly resolved. The preparation processes and mechanism of this luminescent material are described in detail, and some interesting conclusions are presented here.
